You may think this is wind-up but I just bought a licence for PDF-XChange Editor and I have to tell you that this application is incredible. I have to tell you that PDF-XChange Editor is BY FAR the best PDF viewer editor I have ever used, and I've been looking for a viable, fast, no nonsense alternative to Acrobat for decades. It actually make's PDF's (including large CAD drawings and graphics heavy documents) a joy to use, which I never thought possible. It's features, ease of use and common sense, no nonsense design makes Adobe Acrobat look ridiculous.
To whoever designed this application, I just want to say BIG thank you; I've tried dozens of PDF applications over years and they all fall on their face, but PDF-XChange just delivers.
Thanks, this application should be the first choice of anyone that needs to read and edit PDFs without having to bang their head against a brick wall and pay through the nose to do it.
